These are metal film resistors, high quality. One set will do a 9090 or 8080 stereo receiver. It takes two of these sets to do an 7001. This is a set of resistors that will allow you to replace all the fusibles on one F2436 amp driver board. They still work as fuses when overloaded. These resistors are the cause of more blown amp channels than anything else. They can take the heat without drifting up in value over time and ruining your amp.
